This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are asked to formulate a hypothesis, and collect and analyze real research data to understand how quickly natural selection can act on specific traits in a population. Also available in Spanish.

These two activities support the film The Origin of Species: The Beak of the Finch. They provide students with the opportunity to analyze data collected by Princeton University evolutionary biologists Peter and Rosemary Grant.

A hands-on activity that uses simulations with beads to teach students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. Also available in Spanish.
